117 T R O U B L E S H O O T I N G A N D M A I N T E N A N C E Replacing the Drum Unit The fax machine uses a drum unit to create the print images on paper. If the screen displays CHANGE DRUM SOON, the drum unit is nearly at the end of its life. Purchase a new drum unit to replace the current one. Even if the display shows CHANGE DRUM SOON, you may be able to continue to print without replacing the drum unit for a while. However, if there is a noticeable deterioration in the output print quality even before CHANGE DRUM SOON is shown, then the drum unit should be replaced. You should clean the fax machine when you replace the drum unit. WARNING When removing the drum unit, handle carefully because it contains toner. When you replace the drum unit, you should clean the fax machine. (See page 111.) The drum unit is a consumable, and it is necessary to replace it periodically. There are many factors that determine the actual drum life, such as temperature, humidity, type of paper and toner that you use and the number of pages per print job, etc. The drum life is estimated at approximately 20,000 pages at 20 pages per job and 8,000 pages at 1 page per job. The actual number of pages your drum will print may be significantly less than these estimates. Because we have no control over the many factors that determine the actual drum life, we cannot guarantee a minimum number of pages that will be printed by your drum. For best performance, use only genuine Brother toner, and the product should be used only in a clean, dust-free environment with adequate ventilation.
